Q.
To make a crossover using # 6 & #8 turnouts (Walthers
Shinohara code 83), what is the formula for the cut so they
match the 2” NMRA standard?
– James McMahon
A.
There really isn't a 2” NMRA standard for track spacing,
although that spacing is pretty common on model railroads.
3: With a #6 switch sitting on top of a #8 switch, it's easy
to see the difference in frog angles. The tips of the frogs
are aligned. The #6 diverges at a greater angle than the #8,
and the combination will not produce a smooth crossover
if the two are installed face-to-face.
